 // This class is a convenience class for handling editor key bindings defined
 // in gtk keyboard theme.
 // In gtk, only GtkEntry and GtkTextView support customizing editor key bindings
 // through keyboard theme. And in gtk keyboard theme definition file, each key
 // binding must be bound to a specific class or object. So existing keyboard
 // themes only define editor key bindings exactly for GtkEntry and GtkTextView.
 // Then, the only way for us to intercept editor key bindings defined in
 // keyboard theme, is to create a GtkEntry or GtkTextView object and call
 // gtk_bindings_activate_event() against it for the key events. If a key event
 // matches a predefined key binding, corresponding signal will be emitted.
 // GtkTextView is used here because it supports more key bindings than GtkEntry,
 // but in order to minimize the side effect of using a GtkTextView object, a new
 // class derived from GtkTextView is used, which overrides all signals related
 // to key bindings, to make sure GtkTextView won't receive them.
 //
 // See third_party/WebKit/Source/WebCore/editing/EditorCommand.cpp for detailed
 // definition of webkit edit commands.
 // See webkit/glue/editor_client_impl.cc for key bindings predefined in our
 // webkit glue.
